Description
Carbocisteine is a mucus thinner that mainly affects the secretion of bronchial glands at the cellular level, which is beneficial for the removal of sputum. Our carbocisteine API has low impurities and can be directly used to make carbocisteine finished drugs. Its quality has been recognized by many domestic and foreign pharmaceutical companies, and we have obtained the WC certificate for API export to the EU.
